You're sure? That just doesn't make sense to me. There is no
way there is that much caffeine (or polyphenol etc..) in one teaspoon
of green tea leaf. In that same literature we read that black tea has
more caffeine than green, but most people re-steep green tea many more
times than black (at least as far as I know, I really only drink green
tea so some black tea drinkers out there feel free to correct me) so
the green tea drinkers would be getting TONS while the black tea
drinkers would get less.
